The mission of HEC is to serve as the USACE Center of Expertise in the technical areas of surface and groundwater hydrology, river hydraulics and sediment transport, hydrologic statistics and risk analysis, reservoir system analysis, planning analysis, real-time water control management and a number of other closely associated technical subjects. HEC's primary goal is to support the nation in its water resources management responsibilities by increasing USACE’s technical capability in hydrologic engineering and water resources planning and management. In addition to supporting USACE along with Division and District Offices, the HEC provides technical support to the Corps overseas missions to include Afghanistan and Iraq. Additionally, HEC provides services to other Federal, state, local and international agencies engaged in these technical areas. The primary way HEC accomplishes this mission is by developing state-of-the-art software tools bringing them to state-of-the practice that are reliably used by water resources engineers and planners. Since its inception in 1964, HEC has been developing and integrating software tools that support the water resources computing requirements for Corps field offices, headquarters, laboratories, and other Federal, state and international agencies. Over the last 56 years, the software created by HEC has been developed with many software programing languages. Currently, the majority of the coding is done in the Java programming language, but portions also include Fortran, C/C++ and Visual Basic.net. HEC-HMS code development started in 1992 and consists of over 800,000 lines of code residing in over 2000 Java code files. Staff and partners using HEC-HMS have identified features within the model that must be changed in order to achieve higher levels of usefulness and efficiency. The modifications contained in this contract follow on from previous work designed to provide new hydrologic simulation features. At the time, the best information available was used to develop these new features. However, further improvements have been identified and are described within the tasks of this PWS.
